The Razer Viper Mini is an excellent wired gaming mouse. It's the smaller version of the regular Razer Viper and is one of the lightest mice we've tested so far. While its sensor performance isn't quite as good as the other mice in the Viper lineup, it's still superb and its incredibly low click latency ensures a responsive and lag-free gaming experience. Due to its small size, it's best suited for a fingertip grip, and any hand size should be able to use it with this grip type. Unfortunately, it doesn't have as many additional side buttons as the other Viper mice, but on the bright side, every button is programmable.
Our Verdict
The Razer Viper Mini is a decent mouse for office or multimedia use. Its straightforward design feels comfortable enough to last a full work day and it has two additional buttons on the left side which can be reprogrammed. Unfortunately, its mouse wheel doesn't have any L/R tilt buttons or horizontal scrolling to help scroll through Excel spreadsheets. Its scroll wheel is also incremented and can't be unlocked to infinite scroll through long websites or large documents. On the bright side, the mouse is compatible with both Windows and macOS, and while you can only customize it on a Windows PC, you can save your settings on the mouse and use them on a Mac.
- Very lightweight.
- Small design may not be comfortable for larger hands.
The Razer Viper Mini is an ex excellent FPS gaming mouse. It's very lightweight, and its incredibly low click latency means even competitive gamers shouldn't notice any delay or lag. The sensor performance is also excellent, and while its max CPI isn't quite as high as some other options, it's likely still higher than most people will use. Every button on the mouse can be reprogrammed within the software, and the cable is flexible and doesn't create drag on the desk. The mouse is also quite comfortable and should be suitable for any hand size with a fingertip grip.
- Very lightweight.
- Outstandingly low click latency.
- Superb sensor performance.
- Great cable with minimal kinks and drag.
- Small design may not be comfortable for larger hands.
- CPI range isn't as wide and adjustable as most Razer mice.
While the Razer Viper Mini is a good mouse for MMO games thanks to its outstanding sensor performance and click latency, it doesn't have nearly as many additional buttons as dedicated MMO mice. There are only two additional side buttons, though every button on the mouse can be remapped, and you can set a profile switch button to add an additional layer. The Viper Mini should be comfortable and well-built enough to last through the longest of gaming marathons.
